PU Liner Installation Solution

PU polyurethane sheets are typically installed using matching PU bolts to ensure secure fixing and long-term performance.
This combination is widely used in material handling systems where wear resistance and impact protection are critical.

Recommended Installation Method

  • Use PU polyurethane bolts to fix the liner securely onto steel structures
  • Ensure proper spacing between bolts for stable installation
  • Suitable for chutes, hoppers, and conveyor transfer points

Advantages of Using PU Sheet + PU Bolt Together

  • Provides strong and stable installation under impact conditions
